Nina was a writer on Lizzie McGuire, and says she owes her career as a TV writer to stray dogs.

"I found [a stray dog] and took it to the shelter. The woman who ran the volunteer program knew I was a sucker and got me to volunteer. Eventually I met her daughter, who became my friend and mentor and she gave me my first writing job on Lizzie McGuire."

The woman who gave Nina her first job writing on TV turned out to be the very same woman who paired her up with Daisy.

So, Daisy has had a pretty big role in Nina's life, as well as everyone who followed her life on Twitter.

"More than 13 years ago a girl found a dog with no name in a shelter. The dog had been used as a breeding dog and then had been discarded. The girl took that dog home and named her Daisy," wrote Nina's husband, Will, on his blog.

Daisy's health had been deteriorating for the past six months. "She wasn't in pain," wrote Nina, "but going for a walk became going for a stare".

"The seizures which were initially helped by her awesome sunglasses started getting worse. Will and I carried her up and down the stairs, across the street. We laid pee pads as she became incontinent, and we lit scented candles to cover the smell."
